Question

1.) The pile load test data of a 300 mm diameter and 15 m long pile is as
follows . Design a pile group system to carry a load of 4000 kN. Compute
the settlement of the pile group for the designed load.   

Load in kN	0	500	1000	1500	2000	2500
Settlement in mm	0	8.5	16.5	25.5	38.0	60.0

2.) Design a retaining wall for a 8 m sandy soil backfill with unit weight as
17.5 kN/m³ and angle of internal friction 30 degrees. Check the stability
of the designed retaining wall.
